redb is a simple, portable, high-performance embedded key-value database written in pure Rust, loosely inspired by LMDB. It stores data in copy-on-write B+trees and provides fully ACID-compliant transactions with MVCC, savepoints, and crash safety.
Use cases
- embed a persistent key-value store in a Rust application
- replace LMDB or RocksDB with a pure-Rust alternative
- store application settings or metadata with ACID guarantees
- run concurrent readers alongside a writer without blocking
- persist data in no_std embedded environments with custom storage backends
- build a local cache or index with zero-copy reads
When to avoid
- you need SQL or rich queries beyond key-value lookups
- you need a client-server or networked database
- you need multi-writer concurrency across processes
- you need features like secondary indexes or full-text search
